6 because all atomic numbers equal the number of electrons
Not all units of measurement are equal, but the value of each unit is used for its intended purpose, so we have different units of measurement for each problem.
I will have to say that this statement is true
Answer is: A) The solution turns blue litmus to red.
Sulfuric acid (H₂SO₄) is a strong acid, it means that the solution of sufuric acid is more acidic (pH<7) than water (pH = 7).
Chemical dissociation of sulfuric acid in water:
H₂SO₄(aq) → 2H⁺(aq) + SO₄²⁻(aq).
When solution turns phenolphthalein pink, it means it is basic (pH>7).
Sulfuric acid has more hydrogen ions (H⁺) and less hydroxide ions (OH⁻) than water.
Answer:
An exothermic reaction releases energy. Endothermic takes in energy.
